【中文标题】Rails 执行迁移 ArgumentError【英文标题】：Rails Executing migration ArgumentError 【发布时间】：2015-01-26 13:13:32 【问题描述】：

我在执行 rake db:migrate 时遇到了一个奇怪的问题

== 20141127213559 CreateMovies: migrating =====================================
-- create_table(:movies)
   -> 0.0033s
== 20141127213559 CreateMovies: migrated (0.0034s) ============================

rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

wrong number of arguments (1 for 0)
ArgumentError: wrong number of arguments (1 for 0)

Tasks: TOP => db:migrate
(See full trace by running task with --trace)

我所做的是：

rails generate model Movie

然后编辑迁移 CreateMovies

class CreateMovies < ActiveRecord::Migration
  def up
    #drop_table :movies
    create_table :movies do |t|
      t.string :title
      t.string :rating
      t.text :description
      t.datetime :release_date
      # Add fields that let Rails automatically keep track
      # of when movies are added or modified:
      t.timestamps
    end
  end

  def down
    drop_table :movies
  end
end

这是使用 --trace 执行命令的输出

[fran@arch rottenpotatoes]$ rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate

任何帮助将不胜感激。谢谢。

【问题讨论】：

您的迁移文件看起来没问题，您是否再次使用--trace 重新运行迁移以查看完整错误？我刚刚编辑了初始线程并将输出与--trace 【参考方案1】：

如果您使用的是 Rails 4.2.0.beta4，ActiveRecord 将需要 arel gem。将以下内容添加到您的 gem 文件中

gem 'arel', '6.0.0.beta2'

然后运行

bundle install

您可能会收到以下错误消息

You have requested:arel = 6.0.0.beta2

The bundle currently has arel locked at 6.0.0.
Try running `bundle update arel`

然后

bundle update arel

现在您应该可以运行迁移了。

您可以在这里找到类似的解释性答案：Can't migrate database after scaffold. Section 2.2 Ruby on Rails Tutorial Michael Hartl

【参考方案2】：

也许你应该在创建电影表后执行这个：

generate migration AddFieldsToMovies newfield:type

这会生成正确的迁移，请参阅：
